China successfully launches new ocean observation satellite

China on Wednesday successfully sent a new ocean-monitoring satellite into orbit as part of its effort to build an all-weather and round-the-clock dynamic ocean environment monitoring system which would provide early warning on marine disasters.

The satellite was launched by a Long March-4B rocket carrying the Haiyang-2D (HY-2D) satellite from the Jiuquan Satellite Launch Centre in northwest China, the state media reported.

The HY-2D will form a constellation with the HY-2B and HY-2C satellites to build an all-weather and round-the-clock dynamic ocean environment monitoring system of high frequency and medium and large scale, Xinhua reported.


The constellation will support the country's early warning and prediction of marine disasters, sustainable development and utilisation of ocean resources, effective response to global climate change as well as ocean research.

The HY-2D was developed by the China Academy of Space Technology, and the carrier rocket by the Shanghai Academy of Spaceflight Technology.

Wednesday's launch was the 370th by the Long March rocket series, the report said.

China's space programme made significant advancements last week when it landed a spacecraft on Mars, becoming the second country after the United States to have a rover on the red planet.
